I have recently written article “How to Convert Huawei E3276 Hilink modem into normal Modem using firmware upgrade“. Today, I am writing another great article to repair Huawei E3276 dead modem using firmware upgrade process totally free. Recently, Huawei has launched normal modem as well as hilink modem, but model was same, and it created too much confusion between the users. As you can find the Huawei E3276 Normal modem as well as Huawei E3276 Huawei Hilink modem also in the market. There are too many firmwares are available over the internet as I have provided all types of E3276 firmware in this article.

Because of the confusion and little knowledge, various users formatted his normal modem with hilink modem (Normally, Hilink modem firmware starts from 22 and normal modem firmware starts from 21). After the updating of the Huawei Hilink modem firmware in Huawei E3276 normal modem , it stops working, also in firmware update it will successfully update your modem. One person posted in forum that he has got the success in flashing the dead E3276 modem with normal firmware and now his modem is working fine.

  4. Hi KUMAR ,
    my modem had software HiLink , I decided to change it to a normal
    so just update the dashboard and not the firmware , now my modem does not
    connect to internet but if you install and detects their drivers ( windows
    mobile -based Internet sharing device) , I want to update or change to normal firmware i have error ( Error Code10 , find port failed ) , does
    not detect the port …. the same way when I want to install the software o dashboard HiLink …….. Might help me how to solve this problemaa .. ??

    • You have made a big mistake, Hi-link and normal modems are two different types.
      Check in computer management and if any Huawei ports are showing in yellow colour then install the drivers properly, then try.

  5. I know it, i have made a big mistake, but I would like to fix it and I think there must be some way to fix it. in the device manager don´t have any ports huawei and no yellow showing a lack of driver . when i plug modem to usb port don`t showing no other USB or COM port, only windows mobile-based internet sharing device. modem green light blinking, if i put provider card into modem, light start green blinking to blue (UMTS and LTE signal is found).
    thanks kumar….if you get me some other advice I`ll be very gratefull you, but I’ll continue looking for more info to solve this problem.

  6. Thanks for the quick respone, i-m trying to make E3276 as USB modem and disable hilink, is it possible right , even when the drivers are for E303? do you have another tutorial for this modem? Thanks in advance.

    Best.

  18. Dear Kamlesh,

    hope my mail finds you well.

    I have one Huawei E3276 Modem, i had to enable the Diag Port using the Dc-Unlocker; but i inserted the below command by Mistake : “AT^SETPORT=”A1,A2;1,2,3,5,A,10,12,13,14,16,A1,A2” which disabled all Modem Ports 🙁

    i tried your link to fix my issue “https://unlock4modem.in/repair-huawei-e3276-dead-modem-using-firmware-upgrade-free/ “; but it didn’t work to enable the disabled ports.

    the problem that i don’t have the AT Command Port to Enable the Ports again, i tried everything of Flashing the Original Firmware for Normal Not Hilink E3276 Modem and Also, The Original E3276 for Hilink Modem, Different Modems FW and all with the same Error that the No Ports had been Detected.

  20. hi, thx for the great article.
    I have a dead huawei pocket wifi model E585-82u, its gone dead when I was trying to update the firmware. but an error happened then now is just freezing on three logo. now, when I connect to pc it shows unknown device. is there any way to repair it without J-tag device?
    hope, you help me with this.
    my regards.

  21. hello kamlesh wholeheartedly appreciate that you helped me get my device

    when installing the HiLink gives me an error and asks me password

    could you help me please??

    device: E3276
    IMEI: 863781016285190

  22. Hey, Kamlesh

    I stumbled upon the internet trying to find a way to resurrect my E303C. Yeah, I know that’s about E3276, but there’s quite a lot in common betwixt these devices, you know… My problem is: like others here, my modem connects only as CD-ROM mode on Windows, and as Hilink mode on Linux.

    Well, it worked well before I tried to flash that, uh, 21.x version (but it already had 21.x, anyway). The update wizard failed, giving me error 16. It disconnected and reconnected as CD-ROM to never get back to serial mode. In Linux, I can access “switchProjectMode”. It gives a blank page, as expected, but won’t do anything. It stays connected as Hilink CDC device no matter what.

    I’ve already tried with usb modeswitch and everything I could get from Google. But it stays as it is. Is it bricked? There’s a green light blinking every 3s.

  23. Hi Kamlesh, I tried your steps, but after all my modem E3276s-920 is still not recognize (no COM port). Is kind of working, just in Edge, but without the Partner Software. Is possible force a recovery?

      • I’m stock with E3276s-150_21.263.30.02.103, but i tried with many version with the same result: E3276S-150 Update 21.491.05.00.00 (Universal) | E3276s-920 21.260.03.00.00 (normal)

        • You want to say at present in your device firmware version E3276s-150_21.263.30.02.103 is installed, which is from Switzerland swisscom. Any idea what was the firmware version you had installed by default.

          • I’ve no idea 🙁 , but I’m from Peru. I’m wondering if is possible to force a recovery without a COM port detected? Because if it was possible to update to a Switzerland version maybe is possible to update to another version right?

                    • I discoverd something strange, when I update the modem with E3276s-150_21.263.30.02.103 the conmputer detect 2 new COM ports (3G application interface and UI), but when the update is finish those ports disappear.

                    • When it was updating with Switzerland version I can recopile this:

    • You have installed firmware 21.436.03.00.00, which requires Huawei mobile partner to communicate with PC. First install the Huawei mobile partner in your computer, then again flash the firmware with any another.
